ABSTRACT:
A torsional vibration damper is designed with a driving-side transmission element, with at least one planet carrier which can rotate relative to the transmission element and which planet carrier is provided with at least one plane wheel which is engaged on one hand with a sun gear and on the other hand with a ring gear, and with a driven-side transmission element. One of the transmission elements has control means for a spring device. There are centrifugal masses corresponding respectively to the driving-side transmission element and to the driven-side transmission element, at least one of which centrifugal masses is connected by means of the spring device to at least one element of the planetary gearset which acts as an intermediate mass, whereby the intermediate mass can be driven in a movement which is a function of the speed and direction of rotation of the two centrifugal masses with respect to one another.
